Talking about the three major inspection and maintenance of deep winter automobiles

Recently, the country has cooled down in a large area. While we are adding clothes, it is time for a vehicle inspection and maintenance for our car. As the saying goes, three separates and seven separates. If the car is not well maintained, its performance will be greatly affected.

If your car has obvious scratches and scratches, it should be painted in time. Because the role of paint is not only beautiful, its more important function is rust prevention.

Pick a sunny day and do a whole car waxing to maintain the paint surface of the car. For areas that have been stained, do not polish them multiple times, but do the paint again.

The tire rubber becomes harder in winter and is relatively brittle. Not only will the friction coefficient be reduced, but it is also easier to leak air and puncture the tire. Check whether the tire has obvious injuries, scratches, and whether the tire pressure is standard. Pay attention to frequently cleaning up the inclusions in the tire pattern and replace the tires with larger wear. In areas with a lot of ice and snow, it is a good way to use winter tires.

Do not forget to check the car lights. If the headlight bulbs become dim, they need to be replaced in time, and the fog lights should not be ignored. Brake lights are more likely to be damaged, so they must be checked and replaced in time.

Also pay attention when using glass washer, and it is better to buy winter special products in colder areas.

If the wiper is used for too long, it must be replaced. In winter, there is a lot of rain and snow, and the visibility is not very good. You must pay attention to the windshield vision.

With the change of temperature, the viscosity of ordinary lubricating oil will also deteriorate with the decrease of temperature, and the increase of frictional resistance when automobile parts are in motion will cause difficulty in cold start of the automobile, decrease of engine power, and even cause burning of bushes and axles. Wait for the accident, and change the oil in winter.

It is more difficult to start the car in winter, and the battery is more likely to lose power. The oxides on the battery poles should be removed to ensure good contact with the poles and eliminate hidden dangers that are not easy to start. For car owners who use liquid-filled batteries, check the height of the battery electrolyte level. If the liquid level is lower than the mark, add distilled water. Cars with insufficient power should be sent to the repair shop for recharging in time.

The antifreeze is changed every two years under normal circumstances. In winter, it is best to go to the repair shop to do a freezing point test to determine whether the antifreeze needs to be replaced.

The heating system needs to be checked and repaired in time if there is something wrong.

Brake fluid is safe and not careless. It must be replaced with good quality winter brake fluid.

It is necessary to carefully inspect the suspension and the front axle to see if there is oil leakage, etc. On the flat ground, use your body to press on the top of the 4 wheels of the car to see if there is any abnormal noise.

Brake pads and brake discs and brake drums should also be checked. Including handbrake system. If there is no problem, use a blow gun from a repair shop to clean the dust on the drum brake. The uneven brake pads should also be polished to make them smooth.

In fact, many of these maintenance items can be carried out regularly through the owner himself. Maybe many owners are busy or neglect to take care of their car. People say that you don’t love cars, and cars don’t love you. The precautions mentioned above are actually very simple, and they are not just for winter.
